Tunnel Executors - Houssam Khelalfa - Bog

The purpose of this book is to present step-by-step requirements and methodology for the construction of high quality tunnels according to project specifications, codes and standards applicable by the NATM method. We began with a generality about the various tunnels and its characteristics; Then we have to present Guidelines and Recommendations for tunnel works. Also, a pilot study has been presented; The geological conditions of the tunnel, seismicity, the kinematic analyzes of the portals, Failure Analysis, Collapse Analysis, Support Evaluation System, Drainage System, Tunnel Support Systems Review with Numerical Analysis Methods, Analyzes with Phase 2D Program, Evaluation of Analysis Results, Analysis of Vehicles and Pedestrians Passages, Reinforcement details of the lining (Coating) and the concrete slab, Static calculation of the open trench structure and soil nail design calculations. Then we present with details how to make and apply the Realization, Monitoring and Surveillance of a Tunnel, such as; Coating Classes, Drawings, Tunnel Portals, Tunnel Excavation Method, Auscultation and Deformation Monitoring Inside tunnel (Convergence). Finally; we present with details how to make and apply a Quality Assurance Plan (QAP) and its detailed procedures necessary to reserve and meet the quality requirements for the good control and development of tunnel construction works.
